RGB512¶
This is the first in a series of generative art collections to be published on OpenSea.
This collection, entitled RGB512, consists of 16 RGB images of 512 x 512 size generated by simple functions of the form $ (x,y,\theta) \to (r,g,b) $ that map the two coordinates of a pixel ($ x $ and $ y $) and a random number $ \theta $ (extracted from the uniform distribution $ [0,1] $) to the 3 RGB channels.
Every image is generated by three handcrafted formulas, one for each channel:
$ \left\{\begin{align} &r = f_R(x,y,\theta) \\ &g = f_G(x,y,\theta) \\ &b = f_B(x,y,\theta) \end{align}\right. $
Every channel function $f_C$ may include:
- a combination of x and y => tagged as XY:C
- a trigonometric function => tagged as TRIGO:C
- a logarithmic function => tagged as LOG:C
- a modulo operator => tagged as MOD:C
- a random number => tagged as RND:C
The 5 tags constitute a vector that characterizes the pattern of the image crated by the channel functions. To ensure a pattern variability in the collection which gives a character of uniqueness to each item, every image has been generated using a specific vector of characteristic tags.

Prepare collection for publishing¶
The 16 images have been generated as PNG files and published on OpenSea as NFT on the Polygon chain.
Each image has a unique characetristic tags vector. Several images may share some tags while others are the only ones to have a specific tag. The latest are listed below and are tagged also in the OpenSea using the properties slot in item metadata.

Project perspective¶
This is the first visual abstract generative art I created to be published as NFT. This is also my first exploration in creating NFT at all.
More collections of generative art will be realised, also according to the reactions to this first one, following different inspirations, approaches and algorithms to ensure that every collection is unique and distinguishable from the others.
Notes:
- The code used to generate the collection has been written in Python using a jupyter Notebook.
- This project page has been realised converting the original NFT RGB512 Notebook in HTML using nbconvert (the code has been hidden for readibility)
- The source code is available in the same github public repository
